'lo the upper. end of lhls \crliml longitudinnl shaltislixed n lun'izonln-l grc-nr-wlu-el, ll whinh meshes with a Sll1'lllil l vertical gear-wheel or 41 segnienl-nl rock, 17, that is fixed to the inner face 0! one of the signnl arms or blades, preferably the blade 7, to operate the shaft 5 and both signal-blades; or, if desired, this gearwhecl or rack 17 may be fixed to the horizontal transverse shaft An operating-lever is fixed to the vertical shaft 1a at a pointimmediatel y above the top 2 of the vertical stand. This lever is made in two parts or members, the inner one, 18, of which is fixed to the shaft 14 and the outer member, 19, is pivotedto the outer uncon lined end of the inner member, 18, and is adapted to be adjusted at right angles thereto to lock the lever and the shaft 14 against movement. 7

My invention is especially adapted for use in connection with a tlu'ee-throw switch of a railway-track, and with this end in view the lower end of the vertical. shaft/14 may be provided with a crank, as shown, or otherwise adapted for connection with the switch; but I do not desire to confine myself to this particular use of in invention, as it may be used with equal advantage in other relations or nn' d er diiferen t conditions.

The operation of my improved .railway-signal is as follows: The signal arms or blades normally remain in the vertical position indicated in Fig. 'l and theoperatinglever assumes the positions shownin Figs/'1 and 2. To throw the signal arms or blades to an inclinedposition on one side of the post, (indicated by the dotted lines A in Fig. .l,) the lever 1819 is moved to the left and in the po sition indicated by A, which movement of the lever turns the shaft 1 t and the gear-wheels to move the signal l'llades or arms to the positions indicated, whereby the lenses in one of the arms, 8, of the two blades are adjusted or moved in line with the lenses of the lamp 1.3. When it is desired to give a signal of another character, the lever is moved from the left or the middle position to the right of the post 3, as indicated at B, which thereby turns the shaft ll and the signal arms or blades, the blades assnm ing a reverselyd ncl-ined position on the opposite side of the vertical post, as'

indicated by dotted lines at B, and having the lenses in the arms 9 thereof adjusted in line with the lenses of the lamp.

Changes in the form and proportion of parts and details of construction can be made without departing from the spirit or sacrificing the advantages of my invention.

The top 2 of the switch stand is provided with a series of notches, 20, (see Fig. 3.) which are located at suitable intervals to receive the outer member, 19, of the operating-lever after the lever has been turned horizontally to properly adj ust the signal arms orblades and when said member 19 is turned to a vertical posit-ion. It will be understood that the outer member, 19, of the lever is turned to a horizontal position in line with the inner member, 18, thereof when it is desired to turn the lever to adjust the signal arms or blades in order that said member 19 may clear the top of the stand 11, and that said meinberlf-l is turned to a vertical position after the arms or blades are adjusted, so that it fits in one or the other of the notches 20 in the stand 1 to lock the lever, the vertical shaft, and the signal arms or blades against movement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a railway-signal, thecombination of a vertical post, a signal-blade, 6, having the diagonal arms 8 p ov edwith lenses arranged on opposite sides thereof and pivoted on the post at a point between said diagonal arms,a fixed lantern arranged at one side of the signal-blade and in the vertical plane of the,

pivot thereof, and mechanism for moving said signal-blade to an inclined position on either side of the post, and thereby adjusting, one or the other of the lenses of said blade in line with the lens of the lantern, substantially as described, for the purpose set forth.

9. in a railway-signal, the combination of a vertical tubular post, the two signal arms or blades 6 7, carried by a common horizontal shaft which passes centrally therethrough, and each signal-blade having two reverselyinclined arms, 8 9, each provided with a colored lens, a stationarylantern 011 the post arranged between the two signal-arms in. the vertical plane of the pivot thereof, and avcrtical shaft geared directly with the signal-blades for positively moving the latter to an inclined position at either side of the post and adjusting one or the oth r f e two lenses carried by each blade in line with the lenses of the lantern, substantially as and for the purpose set forth.

In a railway-signal, the combination of a fixed stand, 1, having the vertical. tubularpost 3 fixed thereto, a horizontal transverse shaft j ournaled on the post at the upper end thereof, the signal-blades each having the diverging lens-holding arms 8 and 9, fixed on said shaft at a point between the arms thereof, a

lantern fixed between said arms in the vertical.-

plane of the horizontal. shaft, avertical shaft, 14, passing through the tubular post and geared at its upper end directly to one of the signal-blades, and a lever, 18 19, fixed to the vertical shaft, substantially as described.

In testimony whereof I at'fix my signatu re in presence of two witnesses.
